HANDLE FOR CROSSCUT-SAWS.

QPECIEICATION forming part of Letters Patent No. 375,916, dated January3, 1888.

Appication filed September 8, 1887. Serial No. 249,130. (No model.)

To all whom it may concern.-

Be it known that I, llIARTIN BENNETT, acitizen of the United States,residing at Eureka, in the county of Humboldt and State of California,have invented new and useful Improvements in Handles for Grosscut-Saws,of which the following is a specification.

- My invention relates to improvements in handles for crosscut-saws; andit consists in a certain novel construction and arrangement of parts,fully set forth hereinafter, and specifi' cally pointed out in theclaims.

In the drawings, Figure 1 is a perspective view of a portion of a saw,showing my improved handle attached thereto. Fig. 2 is a horizontalcentral sectional view of the same. Fig. 3 is a vertical transversesection taken through the bolt.

Referring by letter to the drawings, A designates the clamping-plate,comprising the, leaves 13 B, which are spread at the outer or rcarendsto form the sleeve or socket O, to receive the lower end of the handleD. The leaves B B are hinged together at the outer ends (on the outerside of the sleeve or socket) to enable the front ends of the same to beseparated, for a purpose hereinafter mentioned. The leaves B B are alsotapered from the rear ends toward the front ends, at which point theyare very thin, and at the said front ends the leaves are provided eachwith a series of perforations, E, which are aligned, respectively, witheach other. The leaves B B are further provided with alignedlongitudinal slots G G, for a purpose to be specified.

H designates the blade of the saw, which is provided at the end with thelongitudinal slot H, longer than the slots in the leaves B, but alignedtherewith, and also with a series of perforations, h h, to align withthe perfora tions in the inner end of the leaves B. Rivets are adaptedto be passed through thealigned perforations.

I designates a washer-plate adapted to bear against the outside of oneof the leaves B, and

it is provided on the inner side with the lugs K K, having an openingorspace, K, therebetween, the said lugs being tapered or beveled on theouter sides and adapted to project through the aligned slots in theleaves B and the saw. The washer-plate I is provided with a centralopening, 2', aligned with the opening between the lugs K K on the rearside.

L designates a bolt adapted to pass through the opening K between thelugs K and the opening 6 in the-center of the plateI, and it is providedon one end with the cross head or arm M, adapted to slide between thelugs K and bear against the outside of the leaf B on the opposite sidefrom the washer-plate I. The said cross-head M is provided on each endwith an inturned flange, N, adapted to pass up along the sides of theclamping-plate A and prevent the edges of the saw-blade from projectingbeyond the edges of the clampingplate. A wing or thumb nut, O, isscrewed on the threaded end of the bolt Land adapted to bear on thewasher-plate I, and when the former is screwed down tight the cross-headwill be drawn tight against the opposite side of the clamping-plate anddraw the hinged leaves of the same firmly together to clamp against theopposite sides of the saw-blade. It will n0w be seen! that when thesaw-blade is secured between the hinged clampingleaves and pinsor rivetspassed through the aligned openings in the blade H and the leaves B Bthe former will be very firmly secured to the handle, and the saidsecurement may be accomplished in a very short time. When the clamp isto be applied to a saw, the leaves B B are separated, the handle Dplaced in the socket, and the end of the saw placed properly between theleaves. The rivets or pins are secured in the aligned perforations, thewasher-plate placed in position, with the lugs on the rear side thereofpassed through the slot, the bolt passed through the opening in thewasher-plate, and the wing-nut screwed on the threaded end thereof.

The device is very simple and will be found verystrong and effective.The object in-providing-the slot in the saw longer than the slot in theleaves is to-enable the handle to be applied to anysaw. The distance ofthe perforations from the slot may Vary in differentsaws, and therefore,if thelatter is made longer than necessary, the handle may be readilyfitted to any saw.-

Having thus described my invention, I claim- 1. The combinationmith thesaw-bladehaw ing the perforations 7th and the slot H therein, of theclamp A, comprising the leaves B B, having the socket O in the outerend, the perforations E in the inner end to align with the perforations7t 71, and the slots G G, to align with the slot in the saw-blade, theplate I, having t-helugs K K on the rear side to" pass through thealigned slots, and the bolt L, having the cross-head to operate betweenthelugs K and the wing-nut to screw on the threaded end thereof and drawthe leaves B B together to clamp the saw-blade, substantially as and forthe'purpose specified.

2. The combination, with a saw blade having the slot Htherein, of theclamp A, comprising the leaves B B, hinged together and provided withthe aligned slots G G to align with the'slot H, the handle D, secured tothe outer end of the leaves, washer-plate I, bearing against the outerside of one of the leaves andhaving the lugs K K on the rear side,whichhave an opening between them to align with a central opening in theplate I, the bolt L, passing through the washer plate and the openingbetween the lugs K, and having a cross-head, M, on the end to passbetween the lugs and bear against the side of the clamp A, and thewing-nut O on the threaded end of the bolt to draw the leaves B Btogether, substantially as and for the purpose hereinbefore specified.

3. The combination, with a saw-blade having the slot H therein, of theclamping'plate A, comprising the leaves B B, to pass on opposite sidesof the end of the said blade, and having the longitudinal slots G Gtherein to align with the slot H, the plate I, to bear against the outerside of one of the leaves, and having a central opening, 73, the lugs KK on the rear side of the plate to pass through the aligned slots, andhaving an opening, K, between them, the bolt L, to pass through theopenings H and i,'and having the cross head on one end to pass betweenthe lugs K and bear against the clamping-plate, the said cross- M ARTINB ENNETI.
